Abstract
A circuit for voltage multiplication has a capacitor which is connectible via first switching transistors to a supply voltage source and via further first switching transistors in series with the supply voltage source and with a storage capacitor which is connected in parallel to the circuit output. Clock voltages for driving the first switching transistors are switchable in amplitude from a value corresponding to the supply voltage to the value corresponding to the output voltage. In order to achieve high efficiency of the circuit, a clock voltage generator is controllable for amplitude switch over via a supply line which is connectible via a second switching transistor to the supply voltage source and is connectible via a third switching transistor to the circuit output, whereby these switching transistors are driven via the outputs of the comparator which compares the supply voltage to the output voltage. The circuit may advantageously be employed in hearing aid circuits.
